TOILET SYSTEM FOB VESSELILS.

Application filed January 5, 1924. Serial No. 684,618.

To all whom it may concern:

Be it known that I, ALBERTCHRISTEN, a citizen of the United States, anda resident of I-Iastings-omHudson, in the county of Westchester andState of New York, have invented a new and ImprovedToilet Sy tem forVessels, of which the following is a full, clear, and exact description.

This invention relates to improvements in toilet systems, and hasparticular reference to a system to be used on vessels.

An object of the invention is to provide an improved system of simple,practical and eifcient construction, in which water is pumped to andfrom the bowl in such a manner as to effectively flush the same andprevent clogging of the system.

The above and other objects will appear more clearly from the followingdetailed description when taken in connection with the accompanyingdrawings, whiclr illustrate a preferred embodiment of the inventiveidea.

In the drawings Figure 1 is a fragmentary sectional view of a vesselshowing thesystem in side elevation.

Figure 2 is a sectional view through the pump construction onsubstantially the line 2-2 of Figure 3;

Figure 3 is an enlarged view, partly in side elevation and partly inlongitudinal section, of the pump construction and the operating meanstherefor;

Figure 4 is a transverse section on the line 4.-4 of Figure 3: and

Figure 5 is a similar view on the line 5 of Figure 3.

The invention is shown in connection with a vessel 6 which may be of anyconstruction and in which is suitablv supported at a convenient placethe usual bowl 7 to which is connected at its upper end an inlet 8 andat its lower end an outlet pipe 9.

The pump construction utilized in connection with the present inventionconsists of a base 10 suitably supported at a convenient place andcarrying a casting which includes a force pump cylinder 11 and adischarge pump cylinder 12 arranged contiguous to each other andseparated by a partition 13 which forms one end of the cylinder 11 and awall of the cylinder 12. The opposite end of the cylinder 11 is closedby a removable plate 14 while the end of the cylinder 12 opposite thepartition 13 is closed by the plate 15 having a screw threaded extension16 to which the lower end of the outlet pipe 9 is connected. Theperiphery of the cylinder 12 is also provided with an externallythreaded extension 17 to which is connected'one end of a waste pipe 18,the other end of which is extended through the hull of the vessel 6.

At one end of the base 10 the same is provided with a bracket 19 towhich is secured an operating element, preferably in the form of a highpower electric motor 20 connected in circuit with the source of current21, which circuit further includes a switch 22 of any desired typelocated adjacent the bowl 7 and which, when operated, closes the circuitfor the motor 20 to operate the same. The shaft 23 of the motor 20 isjoined to one section of a shaft 24 by a coupling 25 to rotate the shaft24 when the motor is driven. Said section of the shaft 24 extendsthrough the plate 14 and supports upon its inner end in eccentricrelation to the peripheral wall of the cylinder 11 a rotor 25. Thisrotor is provided with an opening or slot 26 extendlng diametricallytherethrough and in which is disposed a pair of radially movable blades27, the outer edges of which are constantly maintained in engagementwith the wallof the cylinder 11 by the centrifugal force imparted to therotor 25 by the shaft 24. At diametrically opposite points the cylinder11 is provided with internally threaded inlet and outlet openings 28 and29 to which are connected, respectively, adjacent ends of a supply pipe30 and the inlet pipe 8. The opposite end of the supply pipe 30 isextended through the bottom of the vessel and the entrance of water intosaid pipe is controlled by a sea valve 31 of any desired construction.

The other section 32 of the shaft 24 is mounted for rotation in thepartition 13 and one end of said section is utilized to form-a bearingfor the adjacent end of the rotor 25. The opposite end of said section32 extends into the cylinder and supports thereon a rotor 33 throughwhich is ex tended radially on opposite sides of the same a blade 34 theends of which engage the periphery of the cylinder 12.

In operation when the switch 22 is closed to start the electric motor 20rotation is imparted to the shaft 2 f to operate both the rotors 25 and38 and their respective blades. In the operation of the rotor 25, Whichforms a part of the force pump, Water is drawn through the supply pipe30 through the inlet 28 of said pump into the cylinder 11 and: fromthence through the outlet 29 and inlet pipe 8 to the bowl 7. p Thispumping of the Water aids in priming the discharge pump including therotor 83 and as the latter is driven by the shaft 2% the blade 3% Willoperate to discharge from the pipe 9 into the Waste pipe'18.

What is claimed is:

A toilet system for vessels including in combination a bowl, inlet andoutlet pipes connected thereto, a pump cylinder connected to said inletpipe and to a source of Water supply, a second pump cylinder connecteddirectly to said outlet pipe, a Waste pipe leading from the upper end ofsaid second pump cylinderto a point exterior of the Vessel and disposedin a plane above said second named pump, a shaft extending through bothof said cylinders, rotors on said shaft, one disposed in each of saidcylinders, each of said rotors being of such oonjstruetion as to contactWith the side Walls of said cylinder during the entire revolutionthereof, 163115 for driving said shaft, and manually actuatedvmeans foroperating said driving means.

ALBERT CHRIS-TEN.
